https://devzone.nordicsemi.com/f/nordic-q-a/114743/maximum-capacitance-from-nreset-to-ground-on-target-board-connected-to-nrf52-dkOn p. 62, section &quot;5.3.10.1 Device startup times&quot; of nRF52805 Product Specification v1.4, the startup time of the nRF52805 is discussed as a function of the capacitance to ground on a GPIO pin configured as reset (for which we configured P0.21).

As long as the capacitor value is kept small, there should be no issues.. If you connect larger values of capacitance, there can be more current draw in the startup phase of the device..</p> <p>Regards,</p> <p>Swathy</p><div style="clear:both;"></div>
